Evaluating DayCart® 		DayCart®
Chemical intelligence for an Oracle environment

DayCart® provides the capability to standardize chemical information databases around Oracle, the market leader in fully-supported, commercial, relational-databases.

The advantage is clear: the database processes are a function of the Oracle system. DayCart® takes care of the chemistry. The paradigms we use within our cartridge were developed through close cooperation with Oracle, and match those that Oracle developers and DBAs already use and understand.

DayCart's® architecture and design integrates with the Oracle server in a fully compatible fashion. There is no need for any external components to operate. You can use your own tools - such as JDBC - without any changes. These tools will now understand chemistry.

DayCart® is a fully integrated set of tools that extends Oracle clients and servers with chemical intelligence and ability. DayCart® chemical utilities (normalizations, data conversions, comparison functions) supply the pieces required to manage chemical data in Oracle database.

Highlights
  • DayCart® is fast - because it uses SMILESTM, it executes string searches in Oracle, which handles these with optimum performance.

  • DayCart® is fast - because it uses multi-threading technology for the compute-intensive subgraph algorithms (contains and matches).

  • DayCart® is scalable - again because it uses SMILESTM, it has no quantitative limits. It remains robust over data sets of millions of substances. Partitioned indices can be used to further improve performance.

  • DayCart® offers a range of operators on the database (except search, similarity, etc.) from within the SQL language. DayCart® automatically stores and searches reactions - no special add-ons are required.

  • Fast fingerprint indexes for Tanimoto, Tversky, Euclidean distance, and user-defined similarities are provided.

  • DayCart® supports a general interface for adding user-defined functions including property calculations (ClogP, CMR, etc.), data normalizations, and search types. This simple interface model allows the user easily to customize the Oracle system with proprietary algorithms.

  • DayCart® provides optional functions to convert between Daylight and MDL formats for import/export and to compute molecular properties and tautomers.
